Assessment of strength and abrasion resistance of elasto-plastic fiber reinforced concrete using geopolymer based recycled aggregates

Recycled aggregates and geopolymer binders are green materials contributing to the sustainability of planet. We investigated performance concrete using recycled (fly ash (FA) ground granulated blast furnace slag (GGBS)) related their mechanical properties. Geopolymer were prepared by mixing 50% low calcium fly ash, GGBS, sodium hydroxide silicate solution, Coarse aggregate (Natural coarse aggregate, aggregate), Fine (Crushed Sand, Riverbed Sand) elastoplastic fibers. used was obtained locally from Istanbul, Turkey. To explore efficiency during production concrete, partial replacement with natural made in 10, 20, 30, 40%. compare results, containing 100% made. Since gains strength time after casting, On Day-28 Day-90, compressive strength, split tensile flexural those based examined. Results test showed that 28 90 days w.r.t. different ratios 26.8, 25.3, 24.2, 23.1, 23 MPa, 30.2, 28.1, 27.0, 25.2, 25.0, 23.0 Mpa respectively, while 1.9, 1.5, 1.4, 1.4 MPa 2.0, 1.6, 1.5 ultimate tested beams range 3.53 4.54 MPa. Although general produced samples showing a decrement increasing ratio recycle aggregates, results indicated is up some extent 30% beneficial terms strength.
